CVE-2025-71374 · Severity: high · CVSS 8.1 · Published 2026-06-30

picklescan is a security tool used to scan Python pickle files and machine learning models for malicious code. A flaw in the tool allows specially crafted files to bypass its security checks by using a specific Python profiling function. If a user trusts the tool's clean scan result and opens the malicious file, an attacker could gain full control over the user's system.

Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- picklescan (PyPI): upgrade to 0.0.29 or later

  ```sh
  pip install "picklescan>=0.0.29"
  ```


## Technical details

A deserialization vulnerability exists in picklescan due to an incomplete blocklist of dangerous functions. Specifically, the tool fails to identify the 'profile.Profile.run' function when it is invoked within a pickle's '__reduce__' method. An attacker can exploit this by crafting a malicious pickle file (often disguised as a PyTorch model) that bypasses detection. When a victim subsequently loads the file using 'pickle.load()', the embedded payload executes arbitrary system commands. This issue is addressed in version 0.0.29.
